Dyke argued that there was a major opportunity to change the BBC. He said he intends the BBC to have three distinct roles in the 21st century by placing greater emphasis on international and local coverage, as well as national coverage.
According to Dyke: "In the next couple of years, we have an enormous opportunity to really change the BBC. The collapse in the advertising industry is having a profound effect."
He added: "In TV, the ITV system was historically the regional system and the BBC the national system. That will gradually be reversed as the ITV system comes under greater financial pressure. In terms of regional TV news viewing, we are now ahead virtually everywhere, something that was unthinkable, even five years ago."
In reference to digital media, Dyke said the BBC's role would increase over the next decade, becoming increasingly more important as a result of market fragmentation. He said the commercial market will not be able to afford to provide some of the services it has historically produced, services which would fall to the BBC.
Dyke's comments came as he addressed staff about a new phase of his vision for the broadcaster, "One BBC - Making it Happen".
He told staff that the organisation needs to become a better place to work if it is to better understand its audience and reach people it is currently underserving by becoming the "most creative organisation in the world".
Dyke said the company was set to achieve cost-savings targets to reduce overheads to 15% 12 months ahead of schedule.
However, he said that now those cost savings -- agreed with the government as part of a scheme to save £1bn in return for a licence fee increase -- have been met, it was time to "concentrate on audiences, creativity and making [the BBC] a really good place to work".
